摘要：An apparatus for inspecting a pipeline having a pig body (1) which measures aninner shape and a wall thickness of a pipe body (2), travelling inside the pipe body,comprises: at least one distance measuring device for measuring a travelling distance ofthe pig body; a rotation angle gauge (12) for measuring a rotation angle of the pig bodyround its center axis; a plurality of transducers (6) for transmitting and receivingultrasonic beams being arranged in the circumferential direction of the pig body andbeing confronted with the inner surface of the pipe body, which measures the inner shapeand the wall thickness of the pipe body; a recorder (8) of the pig body which storesmeasured data; a signal processing device (10) for processing signals from the distancemeasuring device, the rotation angle gauge and the transducers; and a data processingdevice for analizing the measured data stored in the recorder after the pig body hasbeen taken out of the pipe body.
